The contribution of nuclear energy to reduce the cause of global warming is only 10%

The International Energy Agency (IEA) predicts a strong increase of the carbon dioxide emissions by the year 2030. Additionally, IEA investigated to which extent the above mentioned emissions of CO2 could be prevented if politics applied rigorous measures.

From all measures investigated, nuclear energy was found to have the least effect (only 10%). Almost 80% of the desired effects are due to increasing the energy efficiency.

This result is surprising, in particular if you think about how nuclear power is praised as solution to global warming by politicians like George W. Bush and Tony Blair. It seems like they would (again) head into the wrong direction.

Instead of talking about measures to increase the energy efficiency, which accounts for 80% of the effects, some politicians propagandize building nuclear power plants, which according to IEA can only account for 10% of the desired effects. Here the focus is clearly on the wrong subject!

Global warming is caused by the emission of greenhouse gases . 72% of the totally emitted greenhouse gases is carbon dioxide (CO2), 18% Methane and 9% Nitrous oxide (NOx). Carbon dioxide emissions therefore are the most important cause of global warming.

Recent investigations have shown that inconceivable catastrophic changes in the environment will take place if the global temperatures increase by more than 2° C (3.6° F). A warming of 2° C (3.6° F) corresponds to a carbon dioxide (CO2) concentration of about 450 ppm (parts per million) in the atmosphere.

As a result of the current discussion how further global warming could be prevented or at least mitigated, the revival of nuclear power seems to be in everybody's - or at least in many politician's - mind. It it interesting to see that in many suggestions to mitigate global warming, the focus is put on the advantages of nuclear power generation, its disadvantages are rarely mentioned.

Below is a short summary of arguments for and against nuclear power plants.

Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapour, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect (see below). The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide.

Read on and see graphs about the greenhouse effect and global warming caused by the greenhouse effect.

Definition of global warming: Global warming is the observed and projected increases in the average temperature of Earth's atmosphere and oceans. The Earth's average temperature rose about 0.6° Celsius (1.1° Fahrenheit) in the 20th century, see temperature graphs below.

Does it do any good for Africans suffering from drought if I reduce my personal water consumption? Why should I reduce the CO2 emissions and save energy? Does it reduce starvation anywhere in the world if I eat less?

Living in moderation is «out» because it seems to be full of deprivations and limitations. Read here why it is on the contrary rather full of opportunities for the personal development. It is an indispensable precondition to get in perpetual harmony, joy and (self-)confidence.

Global warming is a typical global phenomena, where the causer of the emission does not automatically suffer from it himself. Cause and effect are separated both in time as well as with regard to geography.

In the past, there was a more or less direct relation between the energy consumption (mainly fossil fuels) and the welfare of a country.

This makes it very difficult to reach consensus between the countries about the required steps to solve the problem. The Kyoto protocol shows that the following of the agreement will be doubtful at best if no automatic sanctions take into effect for countries violating it.

Given the severe consequences of global warming, the above sounds quite hopeless for our future. Read on to see how we all are involved in this and how we can benefit from taking our personal responsibility.

It is not possible for us as human beings to prove the validity of this law either by logic or certainly not by mathematics. It is simply true! Vice-versa however it is also not possible to prove that the basic rights of existence are not valid (which naturally also cannot be interpreted as proof of the validity). Especially in natural sciences and technology we have become accustomed to the fact that we cannot mathematically derive or prove the basic laws. It is true that we can test these basic laws by means of experiments – however this is certainly no real proof of their validity.

To examine the validity of the basic rules of existence we can also carry out certain experiments. We will go through such experiments in our thinking quite soon. Another test option for us as human beings is that each one of us tries for himself to feel whether the basic laws of being are valid. Since we too are part of the cosmos, this truth must be known to each of us. Through your intuition try to feel whether the abovementioned basic rights of existence are valid or not.

Sooner or later – and at the latest shortly before death – everyone will ponder about why we are here, what keeps life going on the earth, how life started, what happens after death, why a plant grows from a seed, whether there are other «inhabited» planets etc. Perhaps we will also concern ourselves with the future of the earth and pose the question of how the many and diverse problems on our planet can ever be solved.

In order – at least to a small extent - to be able to answer such questions, it is important to know what is the actual basis for our being. The answer to this question is astonishingly simple:
